- Abstract:
- The process design, equipment parameters and sludge feeding parameter correction of centrifugal dewatering system for sludge treatment and disposal phase Ⅱ project of Bailonggang sewage treatment plant are introduced. On the basis of practical commissioning, several key factors such as agent dosage, sludge inflow, dilution water, and main engine speed, which affect the water content of the sludge outflow from the centrifugal dehydrator are tested and analyzed. At the same time, the constant torque test of the centrifuge is carried out, and the setting value of constant torque and the target value of the best auxiliary machine torque are obtained. Finally, the operation range of this type of centrifugal dehydrator is determined. The 168 h performance test is carried out in the operation range, and the optimal operation parameters are obtained, which has reference significance for similar large sludge dewatering system process operation.
